Description

Technical Field

[0001] The utility model relates to the technical field of reinforced soil in civil engineering, in particular to a three-dimensional reinforced rubber mixed soil structure. Background Art

[0002] Compared with traditional gravity structures, geosynthetics reinforced soil structures have the advantages of low construction cost, good self-stability and environmental sustainability. Therefore, reinforced soil structures have been widely used in engineering scenarios such as slopes, dams and embankments. The geosynthetics-soil interface is an important component of reinforced soil structures. The interaction between the reinforcement and soil interface has an important influence on the overall stability of the reinforced soil structure. Therefore, the study of the interaction between the reinforcement and soil interface is of great significance to the development of reinforced soil technology.

[0003] The interaction between the reinforcement and soil interface includes the friction resistance between the soil and the reinforcement surface; when there are transverse members on the reinforcement surface that are in lateral contact with the soil, it also includes the passive lateral resistance of the transverse members; when there are open areas on the reinforcement surface, it also includes the interlocking force of soil particles in the open areas. Studies have found that the passive lateral resistance of geosynthetics transverse members plays an important role in the strength mobilization mechanism of the reinforcement and soil interface. Therefore, it is necessary to explore a reinforced soil technology that improves the passive lateral resistance in the reinforcement and soil interface interaction. Utility Model Content

[0024] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0026] In conjunction with the accompanying drawings, some embodiments of the present utility model are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] Example 1

[0028] like Figure 1 As shown, a three-dimensional reinforcement rubber-soil structure includes a rubber-soil mixture and a three-dimensional reinforcement disposed inside the rubber-soil mixture. The three-dimensional reinforcement includes a transverse thickening member 1 and a longitudinal plane member 2, a filling material 3 of the rubber-soil mixture and rubber particles 4, and the transverse thickening member 1 and the longitudinal plane member 2 are integrally formed to form a three-dimensional reinforcement body.

[0029] Three-dimensional components can improve the performance of reinforced soil by providing additional passive lateral resistance and lateral restraint to the soil, and improve the mechanical properties of reinforced soil structures. Therefore, three-dimensional reinforcement has significant advantages over plane reinforcement in enhancing the interface strength and overall stability of reinforced soil structures.

[0030] In this embodiment, the three-dimensional reinforcement material formed by the longitudinal plane member 2 and the transverse thickening member 1 through integral molding includes a three-dimensional geogrid, a three-dimensional geomembrane, a geocell, or a composite reinforcement material formed by a combination of the above three types.

[0031] Furthermore, the three-dimensional reinforcement material composed of the transverse thickening member 1 and the longitudinal plane member 2 can be expanded into a transverse rib thickened three-dimensional geogrid, a node reinforced three-dimensional geogrid, and a node reinforced three-dimensional geomembrane according to project needs.

[0032] like Figure 2 As shown, it is one of the preferred implementation examples of the utility model, the longitudinal plane member 2 is horizontally arranged in the rubber mixed soil, and a plurality of thickening members 1 are parallel to each other and symmetrically arranged about the plane member 2 to form a three-dimensional reinforcement material through integral molding.

[0033] The relationship between the filler particle size and the reinforcement shape parameters will affect the interaction strength of the reinforcement-soil interface. Therefore, the thickness of the transverse thickening member 1 in the present invention is set according to the median particle size of the filler. Specifically, the ratio of the thickness of the transverse thickening member 1 to the median particle size of the fill material 3 is recommended to be in the range of 5-8.

[0034] The rubber mixed soil formed by mixing rubber particles into the filling material has the advantages of small mass, large damping, good durability and low cost. It not only achieves the purpose of secondary utilization of waste tires, but also avoids groundwater pollution caused by traditional methods of treating waste tires. When rubber is mixed into the filling material, the contact between particles is added to the contact between filler-rubber and rubber-rubber on the basis of the original contact between the filling materials. Therefore, the amount of rubber particles will greatly affect the macroscopic mechanical properties of the rubber mixed soil.

[0035] In the present application, the filling material 3 is sand or gravel, which is mixed with rubber particles 4 in proportion to form a rubber mixed soil filler. The recommended volume ratio of the rubber particles 4 to the filling material 3 is in the range of 1 / 19-3 / 7.

[0036] Furthermore, when the particle size ratio of the rubber particles 4 to the filling material 3 is 7, the optimal volume ratio of the rubber particles 4 to the filling material 3 is recommended to be 1 / 10.

[0037] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
